Series "447". Beautiful, colorful worldwide collections on Harris Albums pages, supplemented with additional quadrille album pages. This is a very thoughtfully organized and annotated collections with small sections of early pre 1940 stamps, and then large sections of more recent "like new" mint collections of colorful newer stamps and Souvenir Sheets, occasionally supplemented with Non-Scott listed material. There are 54 volumes in this collection. A true labor of love. Many of the Mint stamps are securely mounted to the page with two hinges.
